Aight my CEL came on the last night and i ran the codes today and it came up with 0201 ingnition signal circuit or primary ignition signal. I was wondering if anyone else has had this come up before and what they did to fix it. any help would be appreciated and id rather not take it the nissan dealer.

The "feedback" voltage of the primary signal from the coils to the ECM is "off"... may be a sign of a failing coil...

I would just clear the code and see if it comes back... if it doesn't, don't worry about it.

 

I did clear it once and it came back after a couple hours of driving.

One of the coils may be going bad... they typically will "misfire" when they get hot...

If the drivability isn't affected, you may just wait until the light comes on more frequently... or you could look for the bad one(s) and replace it/them...

 

how will i know that they are bad, is there an easy way to check them or know which ones i will need to replace?.
